Visual Studio + Analyzers

Im using Visual Studio 2015 together with Unity. I wanted to use roslyn analyzers (StyleCop for example) and addet one through NuGet. Now the Problem is that every once in a while the analyzers vanish from my solution while the NuGet packages are still installed. After searching for a little bit it seems that this is caused by Unity generating the solutions file and thus deleting the analyzers.

I found some older answers (example) where they stop this behaviour through an editor script. But this seems a bit "hacky" to me.

Since then Unity has changed a little bit. So is there now a way to keep the analyzers or prevent the generation of the solutions file?
